Description

Technical Field

[0001] The utility model relates to the technical field of steel structure blasting demolition, in particular to a steel structure blasting demolition device with a protection mechanism. Background Art

[0002] With the in-depth development of my country's urbanization process and energy conservation and emission reduction work, a large number of tall steel structures are facing demolition. The first method of demolishing tall steel structures is blasting. In the process of blasting, in order to ensure the collapse effect, large unit-consumption charges are often used, which will inevitably face secondary disasters of blasting flying objects, seriously threatening the safety of surrounding personnel, equipment and facilities. Therefore, close-body covering protection must be carried out during the blasting of steel structure demolition. Traditional close-body protection measures are generally aimed at low-unit-consumption blasting. Steel pipe racks are set up at a certain distance around the blasting object, and the inside is fixed with materials such as springboards, wooden boards, bamboo rafts, and straw mats to prevent flying objects. Conventional close-body protection measures have the following shortcomings.

[0003] The existing Chinese patent publication number CN203857884U is a near-body protection device used in beam-column steel structure demolition blasting, which includes a protection element and a sunshade net. The protection element is wrapped around the outside of the blasting cut of the steel structure beam and column and tied with galvanized iron wire, and the sunshade net is wrapped around the outside of the protection element and tied with galvanized iron wire; the protection element is composed of a quilt, a braided steel wire mesh and a safety net; the quilt is placed on the bottom layer, the braided steel wire mesh is laid flat on the quilt with the convex surface facing up, the edge is rolled and fixed with galvanized iron wire, and the safety net is laid flat on the braided steel wire mesh, rolled and fixed with galvanized iron wire. This device uses flexible materials, is easy to construct and is not limited by construction conditions. The protection element can be pre-made without affecting the charging and networking construction. There is no risk of secondary disasters and no protection blind spots. The flying objects generated during the large-unit consumption blasting of the steel structure can be controlled within a range of 50m.

[0004] The above-mentioned protective components are not easy to install and fix quickly. At the same time, the use of quilts, woven wire mesh and safety nets cannot fully guarantee the resistance effect, which is not conducive to slowing down the speed of the explosion jet and reducing its impact range, so improvements are needed.
